telegraf do not start at boot when configured in VRF
Closed, InvalidPublicBUG


I recently noticed that telegraf monitoring service does not start at boot time for some reason. Looking at boot log i see 5 quick start attempts in a second with error:

ip[2474]: Failed to load BPF prog: 'Operation not permitted'
systemd[1]: telegraf.service: Main process exited, code=exited, status=255/EXCEPTION
vyos-lns-1 systemd[1]: telegraf.service: Failed with result 'exit-code'.

and after that the service remains in failed state. Checking other services like ntp and snmpd i see the same error at first few attempts to start them. I can't tell what can be the reason, but i see that systemd configuration


fixes that problem for ntp and snmpd. So i'd suggest adding the same Restart/RestartSec to the file
Sample boot log attached.
